Why is it not advisable to use pressurized air for removing metal chips from the milling machine?

It can get jammed under the ways or caught in the spindle taper
It can damage the machine's internal components
It releases harmful vapors into the air
It requires additional safety measures

The correct answer is: It can get jammed under the ways or caught in the spindle taper

Using pressurized air to remove metal chips from a milling machine poses several risks, and the primary concern is that it can get jammed under the ways or caught in the spindle taper. When metal chips are blown around with pressurized air, there’s a high likelihood that they can be forced into tight spaces and crevices within the machine. This can lead to operational issues as the chips might obstruct the movement of critical components, ultimately affecting the precision and functionality of the milling machine. Moreover, allowing chips to accumulate in these areas without safe removal could lead to increased wear and tear on machine parts. Chips that lodge in the spindle taper can affect the tool's seating and alignment, leading to diminished performance precision and possibly causing damage over time. In contrast, although other choices may articulate potential drawbacks or safety concerns associated with using pressurized air, the most immediate risk pertains to the mechanical interference and operational disruption caused by the chips moving to unintended locations within the machine.
